Abstract (en)
[origin: EP3151429A1] The invention concerns an electrical circuit (1) adapted to control a bridge circuit (2) for driving an inductive load (3). The electrical circuit comprises a voltage pulse detector (16, 17), at least one high-side control output (11, 12) adapted to control a high-side switch (5, 6) of the bridge circuit (2) connecting the inductive load (3) with the supply voltage (9), at least one low-side control output (13, 14) adapted to control a low-side switch (7, 8) of the bridge circuit (2) connecting the inductive load (3) with ground (10), an internal control logic (15) controlling the high- and low-side control outputs (11 to 14) and one validation gate (19) per low-side control output (13, 14). The internal control logic (15) controls the at least one validation gate (19) to connect through when the supply voltage (9) falls below a supply voltage threshold, thereby connecting the respective low-side control output (13, 14) with the output of the voltage pulse detector (16, 17).
